WATCH IT!!! Over and over again...
This is one of my all time top ten favorite movies at the Internet Archive.
I've watched at least 4 or 5 times and I'll never get bored of it. Whenever I can't decide what to watch I say to myself - Watch Judge Priest again, you know you can't go wrong with that one...
